@Cassandra Alessio That's great news that there is already water/sewer infrastructure in place!

At times there are news reports of landlords being killed over such matters.And no, the police will not escort you at this time.  

There is actual test standards they undergo.The good news is that thieves are lazy, dumb and lack lock picking skills.

If its as simple as just asking the lender, then that's great news.

This was a primary residence for 8 years, a rental for only one or less.The good news is that it does qualify for the Section 121 Exemption, which is a better plan if you qualify. 1031 essentially passes the buck on the tax bill, Section 121 ELIMINATES the tax bill.It sounds like you qualify - you lived in it as your primary residence for 2 of the last 5 years (actually 4 of the last 5).

In the event that the tenant still doesn't leave, what is the next course of action that I can take?

Well I think the good news is the refi from the deal itself is going to take its rental income into account for the DTI calculation, while DTI from the initial HELOC will not. 

It's possible there are some buyer actions needed in that other form of 1031 I'm not familiar with?

While I agree with you that it 'might' not be the best business practice, I'm genuinely curious-- which law(s) you are referring to that would be violated by the actions you mentioned above?

So I can’t find a simple answer as it’s only one piece of puzzle- as supply and demand have huge impacts.Anyway, the good news is if you are really holding for 10-30 yrs, you don’t have to worry about this (too much).
